History Recap / MyLittlePonyFriendshipIsMagicS6E16TwentyEightPranksLater

* MassiveMultiplayerScam: Pinkie Pie gets the whole town to help her pull a huge prank on Rainbow Dash by making her believe that they all became zombies from the joke cookies she gave out.

* SurpriseCreepy: Opening scene aside, the first half of the episode starts out as cute and colorful as any other episode. Once the zombies show up in the second half, however, the atmosphere shifts into something fitting for a standard horror film. However, [[NightmareRetardant the fear factor is taken away]] (''intentionally'', of course, since this is a kids show) by the use of the rainbow frosting around the ponies' muzzles.

* WhatHappenedToTheMouse: Mr. Cake doesn't show up as a zombie pony even though he was one of the ponies who was pranked earlier in the episode. Which is odd as his wife and children are shown to be apart of the zombie prank.

** The other Mane Five's advice for Rainbow Dash to stop pranking ponies unnecessarily instead makes her think they're challenging her to put more effort into her pranks, and decides to go UpToEleven.

* OverlyPrePreparedGag: Some of Rainbow Dash's pranks show insane amounts of preparation (a massive tiered cake ''and'' a sewing machine shaped cake, sneaking Applejack ''and her bed'' out of her booby-trapped bedroom, collecting thousands of scrolls on a balcony in Twilight's castle) just to prove that her pranks aren't "lazy". The [[UpToEleven most overly pre-prepared gag]], though, is replacing the CMC's [[ScoutOut Filly Guide]] cookies with Rainbow-themed joke cookies.

* HardTruthAesop: While this may sound unjust to Rainbow’s victims, there are going to be pranks pulled on you that you don’t find funny and requesting that the prankster tries to make them funny or even try to make him or her stop can come across as you feeding the {{Troll}}.

* HardTruthAesop: While this may sound unjust to Rainbow’s victims, there are going to be pranks pulled on you that you don’t find funny and requesting that the prankster tries to make them funny or even try to make him or her stop can come across as you feeding the Troll.

* SugarApocalypse: This episode exemplifies the trope no better than a literally sugar-induced ZombieApocalypse with rainbow-faced infectees.

* SurpriseCreepy: Opening scene aside, the first half of the episode starts out as cute and colorful as any other episode. Once the zombies show up in the second half, however, the atmosphere shifts into something fitting for a standard horror film.

* StealthPun: Zombies that have a craving for cookies. You can say they're [[Series/SesameStreet cookie monsters]].

** To be fair though, scaring Rainbow Dash to Hell hardly justifies a Sewing Machine cake prank, a simple brick in the sandwich, a boulder placed on an apple cart and forcing Big MacIntosh to slide down a hill, a skunk on the head, a causing you to fall in the mud, tricking Spike into sending a whole bunch of scrolls to Celestia, and mildly embarrassing Cheerilee. To put it simply, both parties are guilty of this.

* ATasteOfTheirOwnMedicine: Rainbow Dash's friends repay her pranks with a prank of their own with a cookie-fabricated ZombieApocalypse.

* DeadlyPrank: The climax of the episode is Rainbow Dash accidentally unleashing a ZombieApocalypse on Ponyville with her tainted cookie prank. In the end it was being played with because it was a ''faked'' zombie apocalypse courtesy of a MassiveMultiplayerScam. The people of Ponyville were just ''that'' fed up with her pranking.

* MassiveMultiplayerScam: Pinkie's counter-prank on Rainbow Dash entails getting everyone in Ponyville to act like zombies after letting them in on Rainbow's mass-selling joke cookie prank, effectively tricking Rainbow Dash into thinking she's actually started a ZombieApocalypse.

* RealityEnsues: While this may sound unjust to Rainbow’s victims, there are going to be pranks pulled on you that you don’t find funny and requesting that the prankster tries to make them funny or even try to make him or her stop can come across as you feeding the {{Troll}}.

Scared, Rainbow flees Sugarcube Corner, only to find that everypony else that ate the cookies is in a similar zombie-like state, moaning and slowly stalking Rainbow. Rainbow flies to Carousel Boutique to get Applejack, Rarity, and the Cutie Mark Crusaders, and they all flee to Sweet Apple Acres, locking themselves in the barn. Rainbow admits to the prank as the zombie ponies try to break in, saying they should be safe until the effects wear off. But, Applejack, Rarity, and the Cutie Mark Crusaders have also eaten the cookies, and the rest of the town breaks in. As the ponies back Rainbow into the corner, she pleads that she didn't want this to happen, and that this isn't funny anymore. As soon as she does, the town suddenly wipes their mouths clean, revealing they were pranking Rainbow Dash. They concocted the whole thing to make Rainbow see that her pranks weren't being funny, they were being mean, and that she needs to consider other ponies' feelings before going through with them. Rainbow Dash admits the town's prank was good, then says she'll have to do a lot of work to top it.

* RealityEnsues: While this may sound unjust to Rainbow’s victims, there are going to be pranks pulled on you that you don’t find funny and requesting that the prankster tries to make them funny or even try to make them stop in general can come across as you feeding the {{Troll}}.

* DeathOfAChild: In the spirit of the prank. Pound and Pumpkin Cake are a few of the first cookie zombies Dash comes across. At the end, Sweetie Belle, Apple Bloom and Scootaloo "reveal" that they've been turned as well.

* AnAesop: You should be considerate about others' feelings before engaging in any sort of activity that would be funny to one but scary to the others.
